The treatment of non union and delayed union of fractures and also defects resulting from bone cysts or bone tumors by bone grafting is reported and also we have used it. In these Papers the results of bone grafting for surgical treatment of 23 war injured patients with bone lost is reported, and our results were good. 

background: age is one of the most important factors that have consistently emerged as the most potent predictors of mortality and morbidity after coronary artery bypass graft (cabg) surgery. however, early results of cabg in young patients in comparison with elderly ones have been different in previous surveys. the aim of this study was to compare short-term mortality and morbidity in young ve...

Grafting of vinyl monomers onto cellulose is an important tool for the modification of cellulose. Depending on the monomer grafted onto cellulose, it gains new properties. The grafting can be performed in heterogeneous or homogeneous medium. In the grafting performed in heterogeneous medium, the reaction is carried out in aqueous medium using a suitable initiator. As initiator, the radiation or...

Abstract Nanometric metallic stripes allow the transmission of optical signals via excitation and propagation surface-localized evanescent electromagnetic waves, with important applications in field nano-photonics. Whereas this kind plasmonic phenomena typically exploits noble metals, like Ag or Au, other materials can exhibit viable light-transport efficiency. In work, we demonstrate transport...

walnut is one of the most important nut crops in iran. in order to achieve an appropriate and economical production of old seedling orchards of this product, the only fastest and most cost-effective possible option for improving seedling trees is graft operation through top-working using the new improved cultivars in the world. this study was conducted as a  factorial experiment in a randomized...

Acoustic vibrations in tissue are often difficult to image, requiring high-speed scanning, high sensitivity and nanometer-scale axial resolution. Here we use spectrally encoded interferometry to measure the vibration pattern of two-dimensional surfaces, including the skin of a volunteer, at nanometric resolution, without the need for rapid lateral scanning and with no prior knowledge of the dri...

We report on a study of the nanocrystalline structure in Ti, which was produced by cryogenic milling followed by subsequent consolidation via severe plastic deformation using high pressure torsion. The mechanisms that are believed to be responsible for the formation of grains smaller than 40 nm are discussed and the influence of structural characteristics, such as nanometric grains and oxide na...

In view of better characterizing possible quantum effects in the dynamics of nanometric particles, we measure the effect on the relaxation of a slight heating cycle. The effect of the field amplitude is studied; its magnitude is chosen in order to induce the relaxation of large particles (∼ 7nm), even at very low temperatures (100mK). Below 1K, the results significantly depart from a simple the...

ABSTRACT We proposed hybrid nanorobot that can be manipulated by optical tweezers and has hybrid structure integrating functional nanomaterials. We employed femotosecond laser exposure for fabrication of the nanorobot with 3D nanometric structure. We succeeded in fabricating nanorobot with carbon nanotubes (CNTs) that has a high photothermal efficiency. Furthermore, we evaluated optical manipul...
